Biotech beauty is making history with a lab-grown alternative to carmine, the red pigment derived from cochineal beetles. Debut Biotech’s breakthrough could reshape the cosmetics industry — and beyond.
The beauty industry has relied on carmine since before it was an industry; the rich red pigment derived from the cochineal beetle, is used to create everything from lipsticks to blushes. This natural dye, sourced primarily from South and Central America, has remained a staple due to its unmatched vibrancy and stability. However, its origins — requiring an estimated 70,000 crushed beetles to produce just one-fifth of a pound of pigment — have raised concerns among consumers and brands alike. But a new advancement in biotechnology could replicate the dye without its ethical and environmental complications.
California-based Debut Biotech has unveiled a bio-identical, vegan carmine alternative created through fermentation and cell-free technology. Unlike synthetic dyes, which often rely on petrochemicals, or existing plant-based alternatives that struggle to match carmine’s depth of color, Debut says its new molecule is a perfect replica of its insect-derived counterpart. And it is purer, safer, and potentially more cost-effective than the original.
“[Other biotech companies] have tried to do this for 15 years unsuccessfully,” Joshua Britton, founder and CEO of Debut Biotech, told Glossy. “[Carmine] is one of the most complicated molecular structures. From a science standpoint, it is hard.” The challenge, he explained, lay in uncovering precisely how the beetle produces its striking red pigment — a biological mystery that had eluded scientists for two decades. “There were theories on how the beetle did it spanning 20 years and so much scientific controversy, but no one knew,” Britton added.
After investing $10 million and four years of dedicated research, Britton and his team identified two previously undiscovered enzymes responsible for carmine’s signature hue. This breakthrough not only enabled the replication of carmine but also unlocked the possibility of further innovations in beauty, food, and medicine.
The science behind lab-grown carmine
The process of creating bio-identical carmine begins with sugarcane, which is used as a feedstock for fermentation. Unlike traditional biotech methods that rely on genetically engineered microorganisms, Debut’s proprietary approach eliminates the need for live cells, accelerating production and ensuring a higher degree of ingredient purity. According to Britton, natural carmine typically contains only ten percent pure pigment, while Debut’s version boasts a 95 percent purity rate. The new formulation also omits a protein found in traditional carmine that can cause skin irritation, making it an attractive alternative for sensitive skin formulations.
Debut’s innovation is poised to shake up a market that is already undergoing a seismic shift. The global carmine industry, valued at nearly $50 million in 2023, is expected to reach nearly $80 million by 2032. With the rising demand for ethical and vegan cosmetics, biotech-derived alternatives could significantly disrupt this trajectory.
The launch of Debut’s carmine alternative comes at a time when beauty consumers are becoming increasingly conscious of ingredient sourcing and ethical considerations. According to Mintel, 30 percent of U.S. consumers who have used beauty and personal care products in the past year believe vegan ingredients are safer, while 16 percent express a direct interest in learning more about them. Meanwhile, Fortune Business Insights estimates that the vegan beauty sector, valued at $19.12 billion in 2024, could grow to $32.56 billion by 2030.
This shift has prompted major beauty brands to explore alternative red dyes, often turning to synthetic petrochemical-based pigments. However, as Britton noted, these solutions come with their own set of challenges. “Oftentimes when a brand moves away from animal-derived ingredients, they are forced to move to petrochemicals, and that was the kind of link we wanted to break,” he told Glossy.
Beauty first, then food?
While Debut’s carmine will debut in the beauty industry, its applications extend far beyond cosmetics. The announcement closely follows the U.S. Food and Drug Administration’s January ban on Red No. 3, a synthetic food dye linked to potential carcinogenic effects. With food manufacturers now searching for safer alternatives, Debut’s biotech carmine could emerge as a natural replacement — though regulatory approvals for the food industry will take time.
“We always start in the beauty market, because that’s really the best proof point,” Britton told Glossy. “[Beauty industry formulators] understand that the cost [of a new ingredient] will be slightly higher as you enter the beauty market, and then as you keep working on it, the cost will come down to [meet the cost of goods necessary to enter] the nutrition industry.”
As beauty companies integrate Debut’s alternative into their products, the economies of scale could make bio-identical carmine a cost-effective solution for the food industry in the near future. The global biotechnology market, valued at $1.55 trillion in 2023, is projected to skyrocket to $4.61 trillion by 2034, according to Grand View Research. If Debut secures FDA approval, its breakthrough ingredient could eventually become a mainstay in everything from food coloring to pharmaceuticals.
Debut has secured significant backing from industry investors, including L’Oréal’s venture capital arm, Bold Ventures, which has poured $40 million into the company. With a total funding pool of $70 million, Debut is well-positioned to scale production and expand its impact across multiple industries. Its new carmine alternative is expected to be commercially available to the beauty industry by 2027.
